How many joules of energy are needed to heat steam from 100 celsius to 114 celsius?
Approx 2940 Joules.
How many watts is needed to melt one pound of aluminum?
How fast the energy is provided (power, in joules/second or watts) is irrelevant, as long as not too much energy gets radiated away. What you really need to know is how much energy (in joules) is needed.
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
How much energy is needed to convert ice to water on the moon?
none
How much energy is needed to heat 50 liters of water to 50 degree centigrade?
300 calories, which is equal to about 1255.2 joules
How much energy is needed to get a small electromagnet up to 1.6 Tesla it can be in joules watts or volts?
It had better be in joules. Watts and volts are not units of energy. yes, but how many as in ? joules/sec

What energy is measure in?
A: Energy is measured in joules and kilojoules. One joule is the amount of energy needed to lift 100 grams to 1 kiliogram.
How many joules are in 1500 grams?
Voltage is electrical pressure and Joules is a power rating so other info is needed
How many joules of work are needed to life a 15 kilogram mass 3 meters off the ground?
Use the formula potential energy = mgh (mass x gravity x height), mass in kilograms, gravity about 9.8 (meters per square second), height in meters. Answer will be in Joules.
What is the velocity of a 1000kg car if its kinetic energy is 200kJ?
KE = 1/2mass * velocity squared some conversion needed 60 kilometer per hour (1000 meters/1 kg)(1 hr/3600 seconds) = 17 meter per second ================= KE = 1/2(1000 kilograms)(17 m/s)2 = 1.4 X 105 Joules ------------------------
How many kilojoules of energy are necessary to raise the temperature of 3 kilograms of cast iron from 30 degrees celsius to 120 degrees celsius?
I will use this formula. Some conversion will be required. ( I only know specific heat iron in J/gC ) q(Joules) = mass * specific heat * change in temperature Celsius 3 kilograms cast iron = 3000 grams q = (3000 g)(0.46 J/gC)(120 C - 30 C) = 124200 Joules (1 kilojoule/1000 joules) = 124.2 kilojoules of energy needed ===========================
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
How do you convert Mass into thermal energy?
You generally need a catalyst or a mechanism to convert the energy. For example to convert fuel (a mass) into thermal energy, oxidizer and a spark are needed.
What is the amout of energy needed to warm 1 gram of water by 1celsius?
That is the definition of a calorie. It is equal to 4.1868 joules.
How much energy is needed to move an electron in a hydrogen atom from the ground state n equals 1 to n equals 3 in joules?
1.94 x 10-18 Joules
